摘要: Abstract The Nb19Ti40Ni41 alloy has a lamellar structure with bcc-Nb and B2-TiNi phases. It is known that granule Nb phase forms in the TiNi matrix after thermal annealing hydrogen permeability of unrolled annealed higher than rolled alloy, even though two alloys have phase. Although “cube-on-cube” relationship crystal orientation for these phases been observed no specific seen alloy. This indicates between strongly affects Nb-TiNi two-phase alloys.
